UPDATE 4/27: We’ve released Cumulative Update Build 19613.1005 (KB4558320) today with no major changes. This update is designed to test our servicing pipeline with builds from the Active Development Branch in the Fast ring.

The update includes trusted information about the coronavirus pandemic using the search bar in Windows, including a coronavirus info banner in Search Home. Another new feature will allow you to control your music and audio apps from within the Your Phone app.

Fixes:

We fixed an issue resulting in some Insiders experiencing bugchecks with error DPC WATCHDOG VIOLATION in the last few builds. This is also believed to be the root cause of some Insiders experiencing their PC frequently freezing.

We fixed an issue while typing into the browser that could result in the Japanese IME unexpectedly being in Private mode even though the browser wasn’t in inPrivate mode.

We fixed an issue causing many Schannel errors to appear in the System event log.

We fixed an issue resulting in some unexpected characters showing up in the text strings of intl.cpl’s Additional Settings > Currency.

We fixed an issue resulting in stordiag.exe crashing on launch if you tried to open it while running a repro mode trace while filing feedback under the “Disks and Storage” context in the Feedback Hub.

We’re temporarily turning off the new search box in the default apps Settings pages while we work on improving performance and reliability.

We’re updating the VPN connection logic based on feedback, so that if you disconnect from a VPN network, it will now uncheck the option to auto-connect (similar to how it’s handled for Wi-Fi).

Based on feedback we’re updating the text of the Add a Device dialog so the list of examples under Bluetooth includes controllers.

We’re updating the Optional Updates Available section that appears in Windows Update settings, so that you will now be able to copy the text in case you need it.

General Improvements & Changes includes the initial support for DNS over HTTPS, so that you can opt into using encryption when Windows makes DNS queries. Follow the instructions in this blog post to opt in as it will be off by default.

The fix in the build was for an issue causing some devices fail to update with error code 0xc0000409. If you continue to experience this error, please let us know by filing new feedback in Feedback Hub.
